Using SwiftUI as a Language
summary
Claims SwiftUI is best used as a language of grammar primitives not just components, and demonstrates a concrete solution for a production financial app: build a reusable modifier that detects truncation by measuring three ghosts (visible, forced-single-line, fully-wrapped) via background + GeometryReader + fixedSize, then run three comparisons to decide compact/standard/extended. Layout switches use a ZStack with a high layoutPriority winner. Result: no private APIs, accurate selection, and the UI works reliably in the app.
